The main contents of Confucius' moral education are "courtesy" and "benevolence". Among them, "courtesy" is the moral standard, and "benevolence" is the highest moral standard. "Rite" is the form of "benevolence" and "benevolence" is the content of "ceremony". With the spirit of "benevolence", "ceremony" can be truly enriched. In terms of moral cultivation, he put forward methods such as determination, self-denial, practice, introspection and courage to reform. "Learning and knowing" is the dominant idea of Confucius' teaching thought. While advocating being shameless and eager to learn, he emphasized the combination of learning and thinking ("learning without thinking is useless, thinking without learning is dangerous"), and at the same time, he should "apply what he has learned" and apply what he has learned to social practice.
